Claims

[Scope of utility model registration request]

A valve body that is opened according to the amount of fuel supplied is provided in the casing, and a plurality of small holes that are opened and closed by the valve body at one end of the casing and that measure the fuel to be injected, and the small holes. In the fuel injection valve, the plurality of small holes are arranged in a line symmetrical manner, and the injection directions are directed inward from each other. A fuel injection valve characterized by being provided with a guide that divides a nozzle hole and allows fuel to be injected in a plurality of directions.
